Abstract (en)

[origin: WO9940998A1] A high velocity absorber (10) has a lower larger diameter tank section (20) for receiving a slurry at a liquid level (26) in the tank section (20), an upper smaller diameter absorber section (22) where liquid scrubbing agent is mingled with flue gas (44) from which impurities are to be absorbed, and a low pressure drop inlet assembly having a transition structure (24) between the tank section (20) and the absorber section (22) for closing a gas flow path and a liquid flow path between the tank section (20) and the absorber section (22). An inlet housing (42) is connected to and communicates with the transition structure (24) for inlet of flue gas (44) into the transition structure (24) between the tank section (20) and the absorber section (22).
